Specification of Letters Patent.

Patented J une 17, 1913.

To all whom if may concern Be it known that I, FRANK C. Dominnr, acitizen of the United States of America, residing' at Detroit-,in thecounty of lWayne and State of Michigan, have invented certain new anduseful Improvements in Vibrators, of which the following' is aspecification, reference beine; had therein to the accompanying`drawings.

This invention relates to a vibrator adapted for self treatment andarranged either for direct application to the body of the user or forvibrating' the chair, stool or other suport on which the subject may be.

rlhe invention includes adjustments whereby the character and directionof the vibrations may be changed together with other features whichinsurel its easy manipulation.

The invention consists in the matters hereinafter set forth and pointedout in the appended claims.

In the drawings, Figure 1 is a view in elevation of a vibrat-or thatembodies features of the invention showing it attached to a chair or thelike; Fig. 2 is a view in elevation taken at right angles to Fig. 1;Fig. 3 is a view in detail. of an adjustable yoke; and 11 is a view indetail showing; one form of a massage member.

As herein shown in preferred form a slide rod 1 is frictionallv held atone end in one socket 2 of a combined handle and counterweiejht 3. rlheangle of adjustment of the slide to the handle may be varied by shiftingthe slide to another socket if desired, such sockets being` arranged toIrive the necessary oblique relation between the parts. rihe handle isarranged to be adjustably secured on a pivot stud l which passes throughthe body of a clamp 5.. meeting serrated faces indicated at 6 affording'angular adjustment of the parts and a suitable thumb screw or bindingnut T holding' them in adjusted position. If it is desired to pivotallysupport the slide rod, the handle may be reversed in position asindicated by the dotted. lines at 8, in which instance its serrated facebears against the plane face on the hub and permits the handle to swine;on the bolt.

A member for conveying any vibrations imparted to the slide is attachedto the outer end thereof. rThis may take any `desired form, such forexample, as that indicated at 9 which is provided with sockets 10 andset screw 11 common to all, whereby it may be clamped in any desiredposition.

A metal strip is bent upon itself to form a U-shaped yoke having:parallel arms 12 that are connected by a bridge 13 at their outer endsand are apertured to move longitudinally on the rod 1. A pair ofparallel vibrating rods 21 pass through guide apertures in the bend ofthe yoke and aresecured as bv riveting or the like to the bridge 13. Afriction roller 14 is journaled on a cross piece 15 which is in slidingengagement with the rods 21 and is projected against the slide member 1by suitably disposed springs 16 which may preferably be in compressionbetween the bend of the yoke and the cross-piece which may preferably beretained by the rods 21 as keepers. rPhe yoke preferably has roughenedfaces as indicated at 17 to afford suitable finger grip. A bar 18 withcurved sprinp; 19 is adjustable longitudinally on the rods 21.

The clip 5 is arranged to be secured to a chair 2O or the like and alsohas one or more sockets into which the rod 1 may be inserted and heldfrictionally if desired, to use without 'the handle.

The device is operated by grasping the finger grip of the yoke andmoving` it up and down the slide rod, the resultant vibrations of thefree ends of the rods extending from the yoke being` communicated to theslide rod. If one end of the slide rod is inserted in the handle andheld by the user, a massage member on the other end of the slide rod maybe pressed against any portion of the body of the. user to impart thevibrations of the slide rod thereto. Or the slide rod may be mountedeither directly or indirectly in the clamp and the massage memberapplied as before when the slide rod is vibrated by manipulation of theyoke. If the slide rod be secured in the cla-mp and the comparativelyheavy handle be attached to the other end of the slide rod in place ofthe massage member. manipulation of the yoke results in the vibration ofthe chair or other support to which the clamp is attached. As the angleof inclination of the slide rod may be altered, the character ordirection of the effect of the vibrations may be correspondinglychanged. The rapidity of the vibrations may be changed by shifting thecross-piece in or out on the tWo viingly by the springs in contact Withthe slide compensates for any Wear between the slide and yoke and keepsthe parts always in such operative relation that they produce thedesired effect. The device may be easily cleaned and is not liable todisarrangement.

Obviously, changes in the details of construction may be made Withoutdeparting from the spirit of my invention and I do not care to limitmyself to any particular form or arrangement of parts.

What I claim is 1. A massaging Vibrator comprising a handle, a slide rodadapted to be adjustably secured therein, means for fixing the handle indesired angular posit-ion, a yoke having arms in sliding engagement Withthe rod, spring pressed means in the yoke for preventing slack betweenthe arms and the slide rod, and a pair of vibrating rods extending fromthe yoke.

2. A massaging vibrator comprising a slide rod, a yoke having armsprovided With guide apertures through Which the slide rod passes, springpressed means in the yoke bearing against the slide rod for preventingslack between the latter and the yoke arms and a pair of vibrating rodssecured to the yoke to extend transversely to the slide rod.

3. A massaging vibrator compr-rising a slide rod, a handle foradjust-ably securing the slide rod at one end, means for clamping thehandle at any desired angle, a pair of vibrating rods transverse to theslide rod, a yoke to Which the vibrating rods are secured, adapted tomove longitudinally on the slide rod and yielding means'for main tainingthe slide rod and yoke in operative relation.

il. A massaging vibrator comprising a slide rod, a U-shaped sheet metalyoke Whose arms are in sliding engagement With the slide rod, a bridgeconnecting the yoke arm ends, a pair of parallel vibrating rods passingthrough the bend of the yoke and attached to the bridge, a cross piecesliding on the vibrating rods, a friction roller on the cross pieceadapted to bear against the slide rod and springs on the vibrating rodsfor projecting the cross piece and roller against the slide rod.

5. A massaging vibrator comprising a clamp, a Weighted handle angularlyadjustable on the clamp, a slide rod adjustably secured at one end tothe handle, a U-shaped metal strip having parallel apertured arms insliding engagement with the slide rod, a bridge connecting the arms atthe ends thereof a pair of vibrator rods secured to the yoke, a crosspiece sliding on the rods Within the yoke, a friction roller on thecross piece, springs on the rods for projecting the roller against theslide rod and a Weight bar adjustable longitudinally on the vibratorrods.

In testimony whereof I affix my signature in presence of tivo Witnesses.
